IMPROVEMENT IN WATCHMENS TIME-RECORDERS.

Specification-forming part of Letters Patent No. 149,333, dated April 7,1874; application filed February 17, 1873.

To all whom it may concern:

Be it known that I, FRANCIS H. PIAGET, of the city and county of Albany,State of New York, have invented certain new and useful Improvements inWVatchm ans Time-Recorders; and I do hereby declare that the followingis a description thereof, reference being had to the accompanyingdrawings forming a part of this specification, in which- Figure 1represents a view of an ordinary clock (parts of the work not shown)with the improvements in this invention applied. Fig. 2 is a view of thesame taken at line No. 1 in Fig. 1. Fig. 3 is an edge view taken at lineNo. 2 in Fig. 1. Fig. iris a cross-sectional view, on an enlarged scale,taken at line No. 3, in Fig. 1. Fig. 5 is a plan, on the same scale, ofthe several parts of the invention.

My invention relates to a watchmans timerecorder; and consists in thecombinationof feed-rollers, spool, and gear'wheels with the great wheelof a clock, in such a manner as to be capable of feeding the paper overa perforating-pin in proper set times; also, in the combination of alever carrying a perforating-pin, connecting-bar, and a second leverwith a cam and ratchet-wheel, in such a manner as to be capable ofchanging the position of the perforating-pin opposite the paper in alateral direction; and also the combination of the abovementionedelements, in such a manner that, while the paper will be fedlongitudinally over the perforating-pin, the said pin will be moved,with intervals of stoppage, in a lateral direction opposite the paperstrip intended to receive the perforations.

To enable others skilled in the art to make and use my invention. I willproceed to describe it in reference to the drawings and the letters ofreference marked thereon, the same letters indicating like parts.

In the drawings, A represents the frame of the clock. B, G, D, E, and Fare some of the usual wheels and pinions of the train-work of the clock.G is the usual spring employed to give motion to the said train-work.Geared in the great wheel B is the wheel H, attached to the shaft (0,Figs. 1, 3, 4:, and 5, which wheel H is made with any suitable number ofteeth that will cause it to revolve once in six, twelve, or twenty-fourhours, as may be desired or de manded by the length of the strip ofpaper required to be moved daily, yet preference is had for a propernumber number of teeth that will cause it to revolve once in each twelvehours. On the shaft a is fixed a miter-gear wheel, I, making itsrevolutions simultaneously with the wheel H, which actuates themiter-gear J, secured to the shaft 0, carrying the roller K. L is afriction-roller revolving on the shaft 0, and supported by properbearings, in such a manner as to permit its face to contact slightlywith the face of the roller K, as shown in Fig. 4. M is a ratchet-wheel,properly pivoted to the frame-work, as shown in Figs. 1, 2, 4, and 5,and is made with seven, fourteen, or any other proper number of teeth,according to the number of intermittent movements the wheel is to makein each revolution. The said ratchet-wheel is actuated by the pin 0,secured in the center wheel E, Figs. 1, 2, and 5, which revolves once in'lZWQlX'G hours. If a greater number of teeth be made in the saidratchet-wheel M, and its number of intermittent movements in each of itsrevolutions is desired to be made in shorter periods of time, two ormore pins, 0, according to the number of teeth and the time of eachcomplete revo lution of the wheel, may be secured to the said centerwheel, equidistant from each other. Attached to the ratchet-wheel M isthe cam N, which revolves once at each revolution of its attachedratchet-wheel. O is a lever pivoted at d, one end of which levercontacts with the periphery of the cam N, as shown in Figs. 1, 4:, and5, while the opposite end is pivoted to the connecting-bar l whichconnecting-bar is pivoted to the spring-lever Q, carrying theperforating-pin 00, which spring-lever is pivoted at its rear end to anysuitable bracket, f, or part of the frame of the clock. The end of thelever Q carrying the pin .00 is provided with the cross-head 9, soarranged that some portion of the said cross-head will be over thekey-hole, h, Fig. 4, in all the several positions which the lever Q mayassume. It is a spool, intended to receive a roll of strip paper, 8,which is to receive the perforations to be made by the pin :0, when thewatchman shall operate the key.

To operate with this invention, the strip of paper 3 is rolled aroundthe spool B, and its outside end passed between the feedrollers K and L,and between the guard a (surrounding the opening m) and the top plate ofthe frame A, as in Fig. 4. The strip of paper 8 is preferably ruled inspaces, longitudinally, and when the hands of the clock are at twelveoelock, the cam N and its contacting lever 0 will be in position shownby full lines in Fig. 5, and will cause the connecting-bar P to throwthe perforating-point :0, carried by the lever Q, to opposite the loweredge of the paper strip.

The movement of the usual train-work of the clock will cause the pin 0in the center wheel E, at each of its revolutions, to carry theratchet-wheel M forward to the distance of one tooth, when the cam Nwill be moved to a corresponding distance, and throw the lever 0 to alittle distance toward the position of lever 0, shown by dotted lines,which will at feet correspondingly, through the connectingbar I, thelever Q, carrying the perforatingpin 00 which movement will representone halfday, or twelve hours (a. in. or p. m.) The gear H in the while,being actuated by the great wheel 13, will give motion to the rollers Kand L, through the miter-gears I and J, and cause the strip of paper 8to be moved along over the perforating-pin m, which movement of thepaper will be continuous, though slow, and to a length in each twelvehours to be suificient to receive any reasonable number of perforationsto indicate hours and fractions of hours. \Vhen the strip of paper hasbeen fed over a space equal to twelve hours, the cam N will be movedanother tooth, which will, by the levers ()and Q, carry theperforating-pin 00 to another degree ready for any perforation, thus, adfincm, the first, third, fifth, &c., positions of the perforating-pin orpuncture will indicate the time a. 111., and the second, fourth, sixth,&c., positions of the perforating-pin or its punctures in the paper willindicate time p. m., if the said cam is made to have two revolutionseach day.

If desirable, by a slight modification in the time and speed of themovements of the paper on its bed, and the perforatingpin to its severalpositions, the order of indicated time on the paper can be reversed, sothat the perforations across the paper will indicate hours and minutes,while their longitudinal directions will indicate half or whole days.

It is not necessary in every case to use the center wheel E, carryingthe pin 0, to actuate the ratchet-wheel M and its associate cam N, toeffect the required changes of the position of the perforating-pin m, asthe'said ratchetwheel and its cam can be located elsewhere to beactuated by some other wheel, as the great wheel B, or wheel H, or anyother equivalent wheel, which will, by each of its revolutions, effectthe proper movements of the said ratchet-wheel and cam, provided thelever 0 and Q, with their connecting-bar P be modified in theirpositions and arrangements to correspond. Neither is it necessary toarrange the rollers and spool, and the other part of the invention inthe close proximity to the main works of the clock, as shown in thedrawings, as the several parts can be located at a distance from theclock when actuated by any suitable train-work of wheels or equivalentelements.

hen the several parts of this invention have been arrangedsubstai'ltially as above de scribed, the paper strip will be ready toreceive a puncture from the perforatin g-pin at any time, which can beeffected by the watchman thrusting the key XV (shown by dotted lines inFig.4) through the key-hole h, and against the crosshead 9 of the leverQ, and withdrawing the same, when the perforating-pin will be thrustthrough the paper and be withdrawn, leaving an inetfaceable record,which will in the paper indicate the time of the hour and day suchperforation was made.

By the several parts of this invention, a common clock may haveassociated with it a cheap, simple, and reliable means for recording thetimes of the several visitations and operations of the watchman upon asingle strip of paper, which, according to its length, may serve for aweek, month, or longer time, and be preserved for any future referenceor comparison.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

l. The combination of the lever Q, carrying the perforating-pin w,connecting-bar l, lever O, with the ratchet-wheel M and cam N,substantially as and for the purpose set forth.

2. The combination of the rollers K L, gears H I J, spool It, and wheelB, by which the paper strip 8 is actuated, with the ratchet ill, cam N,and lever O P Q, carrying the pin .12, by which the said strip 8 isperforated, as and for the purposes set forth.
